The High Place of Sacrifice in Petra is a cool spot perched high on Jebel Madbah Mountain where the Nabateans used to sacrifice animals to their god. It's like a historical sacrificial altar with killer views of Petra from 170 meters up. You can hike up there in about 40 minutes, check out some ancient ruins along the way, and soak in the dark history of this unique site. Don't miss it if you're up for a bit of adventure and history mixed together!
